Happy new year to those in Australia!
Is it possible for me to assign two-inlet pipes to one Tank using Bentley WaterGems software update 10.00.01.04?I have two inlet pipes that are used to feed one tank all from the top.
You need to specify "Has separate inlet" in the tank properties to TRUE and "Tank fills from top" to TRUE, then you should be able to model tank with two inlets filling from top.
The below has detailed explanation about how to model it along with an example.

That option only allows for one inlet pipe. I can't see where to choose and enter two or more inlet pipes
The "Tank fills from the top" option assumes there is only one inlet pipe. In order to model two inlet pipes, you would need to set up the model with PSVs connecting the tank with short pipes with little to no friction. I would recommend review the link Sushma mentioned. There is a section in that link called "Multiple Inlet Pipes" that gives some information on the recommended setup for a case like this.
